You can check that:
- docker is installed
- docker has network acces (can pull images)
- docker container has network acces
docker run -t lalyos/test
Expected output is: network is ok
This is a self note. Probably never have to be rebuilt
docker build -t lalyos/test https://gist.github.com/99341041e6b513a05ac945c897ef518e.git#main
first version was without a custom image, but its just to long to remember ...
docker run curl -Ls bit.ly/network-test
